Abstract :
A special dipole magnet, which has the leak field less than 5 mT at r=200 mm with the dipole of 0.7 T, has been constructed as a candidate of the KEK B-Factory interaction region magnets. The magnet was energized to the design current of 3871 A without any quench. The multipole components in the magnet bore were measured and the results are consistent with the calculations.<>
